Abstract: In this article, possible options for developing the most economical design of Metal Lattice Tower Supports (MRBO) of power transmission lines at the junction are systematized and investigated. Most of the operated overhead lines have significantly exceeded the service life planned during their design and construction. Therefore, the urgent problem of maintaining trouble-free operation is the repair and replacement of individual MRBOs within the overhead line. The article defines the significant design factors for the delivery, assembly, installation and operation of MRBO structures, taking into account design limitations and manufacturing technology requirements. The systematization, research and analysis of the junctions of the supports were made, taking into account significant factors, especially the type of bolted connections. The option of developing a more economical design with the transition from a single-bolt connection of elements to a two-bolt connection is considered, which makes it possible to reduce the total mass of the structure by 8…12 %. Based on the results of the work, an album of nodes was compiled.
Keywords: overhead power line (OPL), metal support, support shaft elements, support junctions.
Pages: 70-75.
